import React, {Component} from 'react';
import ReactMapBox from 'react-map-gl';
import 'mapbox-gl/dist/mapbox-gl.css';

class MapExample1 extends Component {
    state = {
        viewport: {
            width: "100vw",
            height: "100vh",

    render() {
        console.log("Entering console.log in MapExample1.js ");
        return (
            <ReactMapBox
                {...this.state.viewport}
                onViewportChange={(viewport => this.setState(viewport))}
